Subject: [KASAN, ACPI] 80a9201a59 [ 56.736479] NMI watchdog: BUG: soft
lockup - CPU#0 stuck for 22s! [swapper/0:1]
Hi Alexander,
FYI, here is an old soft-lockup BUG that's is still in linux-next.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit 80a9201a5965f4715d5c09790862e0df84ce0614
Author: Alexander Potapenko <glider@...gle.com>
AuthorDate: Thu Jul 28 15:49:07 2016 -0700
Commit: Linus Torvalds <torvalds@...ux-foundation.org>
CommitDate: Thu Jul 28 16:07:41 2016 -0700
mm, kasan: switch SLUB to stackdepot, enable memory quarantine for SLUB
For KASAN builds:
- switch SLUB allocator to using stackdepot instead of storing the
allocation/deallocation stacks in the objects;
- change the freelist hook so that parts of the freelist can be put
into the quarantine.
